Crane Safety Test Method

Crane Safety Test Method

It is recommended to check the load cable and crane hook for any abnormality first, check twice in turn to ensure that all signs are still as good as possible. Then the Chief Engineer should continue to check the crane hoist operation by pressing the up and down button to operate when no load is abnormal or not.

In the event that we discover major structural cracks, metal deformation, mechanism brakes or any other signs of failure, corroded or cracked hooks and pulleys must be discontinued immediately and conduct processing. Carefully check the power equipment, unstable power source will damage electrical equipment in the crane such as lifting motor, components in electrical cabinets and moving motor.

When checking the load, we need to pay attention that we have to lift the load to a height not greater than 300mm, so keep the load static to check the durability of the metal structure to consider the stability of the crane if it is not safe. have to completely lower the load to handle the problems that have just been considered and discovered.

The crane has a load limiting device to ensure that the lifting load is controlled within the allowable limit, so when the crane is overloaded, the device will automatically cut off the power supply, causing the crane to not work. To operate again, you must manually operate on the crane switchboard to activate and open the source attomat.

Checking the direction of lifting the load is also one of the methods to avoid errors when operating the crane, so it must be lifted vertically because if it is lifted at an angle or at an angle, it can cause damage to the equipment and danger to people standing nearby. lifting objects. When checking during operation, we must observe the cable moving through the pulley to control the crane so that it is not twisted or they do not overlap.

Note that do not stand under the crane hook, load or stand on a lifting object when operating the crane. The crane may slip due to brake failure, broken load cable or tie rope, leading to occupational accident. When lowering the load, it is necessary to stop in front of the floor from 300-400mm and then continue to lower the load. Similarly, when lifting the load, also lift it from 200-300mm from the face, check it is stable and then continue to raise it higher.
